IMPROVEMENT IN WAGON-BRAKES.

Specification forming part of Letters Patent No. 149,189, dated March31,1874; application led March 22, 1873.

To all whom it may concern:

Beit known th at we,WILLIAM BLo OMFIELD andFRANK E. BLOOMFIELD, ofRoaringCreek, in the county of Jackson and State of \Viscon sin, haveinvented a new and Improved Evener-Brake and Holder A ttaehment forWagons,

, of which the following is a specification:

zontal section of a wagon constructed according to our improvement. Fig.2 is a longitudinal sectional elevation.

Similar letters of reference indicate corresponding parts.

A is a draft and brake bar, extending across the tongue B, in front ofthe wheels C, and rigidly attached to the tongue. E is the middleroller, and F the end rollers, and Gr a draftchain, which is coiledaround the middle rollers,l and passes to the guide-rollers at the ends,and has the whiiiietrees attached to it, one at each end. The object isto prevent one horse from getting any advantage of leverage over theother when he gets ahead. The tongue has slotted holes H for thebolt-iron, by which it is connected to the hounds J, so that it can moveforward and back on said bolt. rlhe brake-bar A carries the brake-shoesK, one at each end, which are pressed back against t-he wheels when theteam holds back. These shoes are made double, with two faces, L, onopposite sides adapted to act on the wheels, and they are pivoted by anoblique slot, M, on a journal, N, at the end of the brake-bar, so thateither side can be turned to the wheel by lifting the shoe up as high asthe slot will allow, when it can be readily turnedwithout interferingwith the wheel. O represents the stopbar, which is pivoted to the aXle Pby a yoke,

Q, projecting obliquely backward and downf ward from the axle, andpassing through the stop-bar near the end. This bar has a strong point,which drags on the ground, and enters it when the wagon moves back, andstops it. To lift, it so that the wagon can be backed, it is connected`by a rod, R, with a tongue, B, so that when the tongue is backed the rodR will raise the stop-bar, so that it will not obstruct the backing.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. The combination, with sliding tongue and barO, as described, of a link, R, pivote'd to each, and thereby enablingsaid bar-to be raised by the tongue whenever the horses are backed.

2. The three rollers F E F, connected by links with the bar A, rigidlyattached across the tongue, and coniined with a single draftchain, Gr,all combined substantially as and for the purpose set forth.

3. A brake-shoe having two similar faces, L L, and an oblique slot, M,by which it is rendered reversible, all as set forth.
